2. Adjust the flat level of the unit by adjusting bolts for
installation which are attached in the unit. Make the
drain pipe side lower than the opposite side for smooth
drain.
3. Fix the base plate and back plate of the unit with field-
supplied fixing bolts and screws. When attaching the
adjusting bolts for installation, remove the electrical
wiring box.
4. In case of the RPF unit, perform the above work after
removing the front cover and side cover of the unit.
5. Install the optional air outlet grille of the RPFI unit as
shown in the following figure. If installed in a
comparatively high humid place, condensation may
occur. Therefore, attach a plate which can absorb
water, like SUNKEN AQ made by ASAHI Chemical Co.,
around the grille.

WARNING:
Provide a service access cover which is fixed by
screws so that the fan runner is not directly touched
(Only RPFI model).
CAUTION:
The optional air outlet grille of the RPFI unit can not
be used in a highly humid place like a kitchen,
because condensation may occur on the grille
surface.
